Recombinant human cytosolic carboxypeptidase 1 (AGTPBP1), also known as Nna1 or CCP1. is a metallopeptidase enzyme encoded by the AGTPBP1 gene. It belongs to the M14 family of carboxypeptidases and is characterized by a conserved carboxypeptidase domain alongside ATP/GTP-binding motifs. AGTPBP1 plays critical roles in post-translational protein modification, particularly in the processing of tubulin isoforms by mediating the removal of C-terminal tyrosine or glutamate residues, a process essential for regulating microtubule dynamics and neuronal function.
This enzyme is widely expressed in neuronal tissues, including the cerebellum and Purkinje cells, and is implicated in neurodevelopment and neurodegenerative disorders. Studies in animal models reveal that AGTPBP1 deficiency leads to cerebellar degeneration, ataxia, and loss of motor coordination, underscoring its importance in maintaining neuronal integrity. Mutations in AGTPBP1 are associated with human diseases such as hereditary motor neuropathy and pontocerebellar hypoplasia, linking its dysfunction to disrupted protein homeostasis and cellular stress responses.
Beyond microtubule regulation, AGTPBP1 participates in mitochondrial quality control, autophagy, and DNA repair pathways. Its multifaceted roles highlight its significance in cellular resilience and neurological health, making it a target for research into neurodegenerative mechanisms and potential therapeutic strategies.
